[Updated with info on updated QuickTime codecs] Apple has released Final Cut Pro X 10.0.8, an update to its video editing suite. The code adds several minor features, such as support for Sony's XAVC codec up to 4K resolution, and the ability to display ProRes Log C files from ARRI ALEXA cameras with standard Rec 709 color and contrast levels. Time-reverse clips can now render in the background, and editors can use key commands for adjusting Clip Appearance settings in the timeline, and view reel number metadata in a file's timecode track.

The update is otherwise dedicated to bugfixes. It for instance cleans up green frames generated while rendering with third-party effects, slow performance with some effects and titles, and mono audio files not exporting with proper volume in a surround project. Drop zones should no longer reset to the first frame of a video after restarting the app, and Play Around should work properly on clips viewed through external video hardware. Lastly, Apple has eliminated a glitch that caused poor performance when selecting multiple ranges on a clip.
Paralleling Pro X 10.0.8 are Motion 5.0.7 and Compressor 4.0.7 updates. These, though, are strictly maintenance patches, with the exception that the new Compressor removes a 1GB limit on Vimeo uploads.
(Update) Apple also released updated ProApps QuickTime Codecs, now at version 1.0.2, which includes the following new or updated codecs: Apple Intermediate, ProRes, AVC-Intra, DVCPRO HD, HDV, XDCAM HD/EX/HD422, MPEG IMX, uncompressed 4:2:2 and XAVC. Apple recommends the update for all users of Final Cut Pro X, Motion 5 and Compressor 4.
